thereon. A pair of sprockets 10 which are polygonal in form and corresponding in size with the sprockets 9 are rigidly secured to the shafts 7 and consequently rotate there'- with. Said sprockets are of a uniform size and rotate synchronously. A pair of chain conveyers 11 and 12 are mounted for longitudinal movement on the sprockets 9 and 10 respectively, the former being guided in its movement by the guide-block 5, and the latter by a guide-block 13 secured to the member 3 by means of a screw 14.

A boxblank is indicated by dotted lines 15 in Fig. 1, the spacing of the chain conveyers 11 and 12 being such as to receive the blanks, as will be understood by those skilled in the art. The chain conveyer 11 comprises a series of links 16 which are of a length corresponding with the sides of the sprockets over which the conveyer travels, said links being pivoted together and of such a conformation as to readily receive and hold cleat spacing blocks 17 to be described hereinafter. The links 18 of the chain conveyer 12 are similar to. the links 16 with the addition of a series of threaded perforations 19 which are designed to receive threaded studs 19 having knurled ends 20 as shown in detail in Fig.4. The modified form of stud 21 having a screwdriver slot 22 may be used if .so desired. These studs serve as stops for controlling the intermittent movement of the chain conveyers, as will be explained hereinafter, it being understood that any desired numher of studs may be used and so spaced by means of the perforations 19 as to suit the width of the box-blanks to be run through the machine.

Each cleat spacing block 17 preferably comprises a rectangular base 23 and a vertical rectangular portion 24 having an overhanging extension 25 which is threaded to receive a locking set-screw 26, as clearly illustrated in Figs. 8 and 9. The links 16 and 18 are of channel form, the channel portion forming a seat for the box cleats, not shown. Each link 18 is provided with piv otal holes 27 for the reception of pivotal v pins 28, there being interlocking fingers 29, 110 30 and 31 provided on the ends of the links as shown in detail in Fig. 7. I

feature of the present invention.

. .tric cam the throw of which represents the maximum single movement of the intermittently movable chainconveyers l1 and 12. The mechanism for transmitting this I movement and any desired lesser movement to the chain oonveyers will now be described, this means for transmitting a variable movement constituting the principal The variable feed mechanism comprises a cam roller 34: rotatably mounted in a block 3* and adapted to travel on the periphery of- .the cam for transmitting -motion to the oscillatory arm 35' loosely mounted on the shaft 7, there being a rod 36 connecting The block 36L". is

said block with said arm. maintained in operative position by means of an oscillatory support 37, a pivotal pin 38 connecting said support to said block and a pivot 39 connecting the same with an inward projection T0 of the frame 1. In this manner motion to the left is transmitted to the arm 35, reference being had to Fig. 2-. Return movement or movement to the right is automatically effected by means of a tension helical spring 4:1, the inherent resiliency of which is only suilicient to move the arm 35, red 36, block 3+1',,cam roller 34, and support 37, these parts being light and mounted to move with a minimum of frictional resistance. It will beap'parent that this-limitation of the springwil fis of importance, since if it were too stid ahd powerful itwould overcome the inertia and friction ,of the chain conveyers and cause them to 'move to the right when they are designed to remainin an inert condition during the stapling operation.

' During the movement of the oscillatory arm 35 to theleft motion istr'ansmitted to the chain conveyers by means of .a series of pawls- 42 onev of which automatically engages a tooth 43 of the ratchet wheelll, the latter being 7 adapted to rotate with a sprocket 10 as illustrated in Fig. 2. Said ratchet may be formed integral with the contiguous sprocket or a rigid connection between the two may be elfected, the only re quirement being that they rotate synchronously. A link 45 is pivoted to the oscil1a-.

tory arm 35 at 46"adjacent the rod 36 and extends to the right, asshown in Fig. :2, where a pivotal connection 47 is made with a reciprocatory member 48 which operates on the guide-blocs 13. To the top of the mean ber'48 and arranged approximately at the center thereof is pivoted a bell-crank 49 by r means of the screw. 50, said belkrankconP stalled and the longitudinal wires t'o'be staprising a do: 51 at one end, and a pawl 52 at the then; A leaf spring .33 is secured to the mem er -15 and automatically maintains the .=ellcranlc it) in the normal position as shewn in fig. 1. A stop stud "A on the member is is provided for a'pnrpose to be explained hereinafter.

The operation of the machine is as follows: he stapling apparatus being inpled to the box-blank and eleats'being arranged vertically over the chain conveyers,

the machine is read v for operation. The operator on each side of the machine places the cleats and box'blanksin position during the movement of the conveyers, this placingof the box-blanks and cleats being performed at theright end of the machine, as shown in Fig. 2. During the passage of the box cleats illustrated since any well known type of mechanism may bev installed and operated in a manner as will be thoroughly understood by those familiar with machine; of this :2

character.

Suppose it is desired to transmit a maximum movement to the chain conveyers. then the operative parts will assume the positions as shown in Fig. 2. The cam roller 3* is in the extreme position to the right and will move to the left during a revolution of the cam which rotates as indicated. The motion will be transmitted to'the chain conveyers which will move to the left a distance approximately equal to-the throw of. the cam lVhenthe cam roller 34 passes the highest point of the cam 33 the chain conveyers will stop and the stapling operation will be performed. During this operation the spring 41 will'draw the oscillatory arm 35' and the reciprocatory member 48 back to their initial positions providing that the next movement of the chain conveyers is to be a maximum movement as just described. The stapling operation is accomplished during the time of travel between the highest and lowest positions of the cam roller on the can1, thelatter having a constant rotary. i

full available movement is imparted to the .oonvevers at each operation thereof. "To

aceofijiplish this result the stm'is 19" are; spaced to correspond with the desired spac mg of the staples, any spacing;

the maximum being accomplished by suitably arranging the studs 19 in the large number of threaded perforations 19 provided therefor in the chain conveyer 12. The cam roller will not assume the lowest position as shown in Fig. 2 during these lesser movements since the spring 41 will be incapable of returning the reciprocatory member 48 to the position shown. This is due to the fact that the dog 51 will engage a stud 19 of the chain conveyer before it has completed a full stroke. The action is explained by assumingthat at the beginning of the movement of the chain conveyers to the left that the dog 51 is in contact with a stud 19 as shown in Fig. 1. Then the chain conveyers and dog 51 will move together to the left until just prior to the completion of the stroke, when the pawl 52 will engage the stationary stop stud 54. The dog 51 will now jump over the stud 19' by the combined action of the stop stud 54 and the spring 53. The chain conveyers will complete the stroke when the reciprocatory member 48 and the cam roller 34 will be moved to the left by the action of the tension spring 41. The cam roller will not, however, regain the lowest position on the cam as shown in Fig. 2, since the spacing of the next stud 19 to the right is insufiicient to permit'of their full movement. The dog 51 during its return movement to the right will engage said stud 19 and stop the action of the spring 41, it being kept in mind that during the return movement of the reciprocatory member 48 and the cam roller 34 that the chain conveyers are stationary. Now, the next movement of the chain conveyers to the left will be less than the maximum since the cam roller will not engage the cam until after the same has completed a partial revolution. In a similar manner the succeeding movements of the chain conveyers will be controlled by the spacing of the studs 19'.

A variable feed mechanism of the type set forth is not susceptible of easy derangement of parts and is simple in construction and eflicient in operation.

lVhile I have illustrated and described the preferred form of construction for carrying my invention into effect this is capable of variation and modification without departing from the spirit of the invention.
